Title	166: Effect of q95 on SPI shutdown
Name:	Nicolas Commaux commaux@fusion.gat.com	Affiliation:	Oak Ridge National Lab
Research Area:	Disruption Mitigation	Presentation time:	Not requested
Co-Author(s):	L. Baylor, E. Hollmann, D. Humphreys, P. Parks, N. Eidietis, J. Wesley, V. Izzo	ITPA Joint Experiment :	No
Description:	Use the SPI to inject D2 pellets in an H mode plasma with different values of q95. Experiments carried out last year showed some interesting results concerning the onset of the current quench following an SPI injection. It seems quite different from MGI scenarios. But the data was not large enough for definitive conclusion. This year experiment would provide more data and also by varying Bt instead of Ip, determine the effect of ohmic heating and confinement on these shutdowns	ITER IO Urgent Research Task :	Yes
Experimental Approach/Plan:
Background:
Resource Requirements:	The SPI. Regular tokamak systems. Good beams availability
Diagnostic Requirements:
Analysis Requirements:
Other Requirements:
